ROTARY SPINNING-RING.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed December 19, 1910. Serial No. 598,195.

To all whom it may concern Be known that I, SAMUEL S. DEARBORN, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Rotary Spinning-Rings, of which the following description, in connection with the accompanying drawings, a specification, like letters on the drawings representing like parts.

This invention relates to rotary spinning rings.

In order that the principle of the invention may be readily understood, I have disclosed a single embodiment thereof in the accompanying drawing, wherein Figure 1 is a plan view of a portion of a ring rail provided with a pair of rings embodying my invention; Fig. 2 is a side elevation thereof; Fig. 3 is a side elevation of a form of holder that may be employed in the practice of my invention; Fig. i is a side elevation of one form of shield or casing for the exterior of the ring; Fig. 5

is a transverse vertical section taken through the ring and holder and the exterior and interior ring shields or casings; Fig. 6 is a side elevation of one form of interior shield or casing for the ring; Fig. 7 is a similar view of a slightly modified form thereof;

and Fig. 8 is a plan view of still another slightly modified form of such shield or casing.

An objection to the effective operation of rotary spinning rings has been their tendency to accumulate lint and other foreign matter. Attempts have been made to exclude lint from rotary rings, but so far as I am aware without success. It has been proposed to provide an exterior casing for the ring of a general bell shape, such casing constituting a bearing surface for the ring or with which the ring intermittently contacts during its rotation. In such construction, however, lint has readily accumulated between the outer surface of the ring and the casing. In other cases the ring itself has been provided with a flange or member overlying a portion of the ring bearing, but lint has readily found access to the ring and to its bearing. In still other cases an upstanding sleeve or member has been provided interiorly of the ring, and in most instances constituting an interior support or bearing for the ring, in no case, however,

tomary openings for the spindles.

so far as I am aware has such interior member excluded lint from the ring.

In accordance with the preferred embodiment of my invention I provide a fixed or stationary ring holder having lips or tongues extending within the ring and constituting supports or bearings about or with respect to which the ring rotates with the customary or desired slight axial and radial movements in an ordinary or any suitable manner. An important feature of my invention is the provision of a protector to exclude lint, dirt and other foreign matter from those surfaces upon which the ring rotates. In the illustrated embodiment of my invention I provide both an interior and an exterior protector, which together exclude lint, etc., not only from the surfaces upon or with respect to which the ring rotates, but also from the ring itself from the base thereof sutliciently toward the traveler so as preferably just to escape contact with the traveler in its rotation. It is evident, however, that the vertical extent of the shield or shields employed by me may be varied within the scope of my invention. The upper portion of the ring is kept clear and free of lint, etc., by the traveler both interiorly and exteriorly. Inasmuch therefore as the ring and the surfaces upon which it turns are thoroughly protected, the ring runs freely and evenly.

'While the shield or shields constituting the casing may be variously constructed, preferably and as herein illustrated they do not contact with the ring in its rotation either exteriorly or interiorly. Thereby, I avoid the wear that would be occasioned if the shield or shields constituted a portion of the bearing surface or surfaces, and thus provide an effective protector which uniformly and equally protects the ring and its supporting surfaces indefinitely. Were the shield or shields subject to wear by reason of contact with the ring, it or they would become enlarged in use, and hence less and less effective as a protector by reason of the increasing spacebetween the ring and the protector into which the lint might work.

Referring more particularly to the drawings, the ring rail is indicated at 1 in Figs. 1, 2 and 5, it being provided with the cus- Upon the ring rail I position in any suitable mannor any suitable ring holder. Herein I have shown a holder 2 having a substantially fiat annular base 3, wherein the ring may rest when stationary and a flange 4 having slots 5, by means of which it may be secured by screws 6 or in any other suitable manner to the ring rail. Preferably the holder is provided with clearer, such as 7, which may be if desired struck up from the holder, the latter being preferably constructed of sheet steel. In order to permit the threading up of the traveler, it is desirable to place the clearer 7 at the rear of the ring rail, and it is at this point (that is, at the rear of the rings) where the lint is liable to accumulate as the air currents from the spindle driving drum tend to drive the lint against the ring. The holder is provided with any suitable ring guiding means, such as lips or tongues S bent' upwardly from the base of the holder and received within the ring as illustrated. Herein I have repre sented a ring holder substantially similar to that shown in the patent to E. A. Brigham, No. 956,930, May 3, 1910, but it is evident that any other suitable holder may be employed, inasmuch as my invention is not dependent upon the type or form of holder or ring.

The rotary ring is represented at 9 in the several views, and while it may be of any desired form, it is here shown as similar to that illustrated in the said patent to Brigham. It is provided with the usual traveler race 10 and at its lower end flares outwardly as indicated at 11, and inwardly as indicated at 12, and when in a position of rest bears upon the holder face 3. The lips or tongues 8, which are here shown as three in number and equally spaced, extend within the ring and are represented as flaring outwardly. Their position with respect to the traveler ring is such as to permit the latter to rotate at the proper speed under tension of the yarn upon the traveler, and also to permit the usual slight axial and radial centering movement not herein necessary particularly to describe, inasmuch as the form of the ring'as well as of the supports may obviously be widely varied within the scope of my invention. Although I have shown the lips or tongues 8 as extending within the ring,'it is evident that exterior ring guiding means may be substituted therefor. V

I contemplate the provision of suitable means to exclude lint and other foreign matter' from portions of the rotating spinning ring herein for convenience termed the traveler ring, and preferably from both faces thereof below the path of the traveler as well as fromthe base or support whereon the ring is rotatable. To eflect' this result, I have in the described embodiment of my invention employed an outer shield 13 preferably of annular form and herein shown as conforming substantially in shape to the outer face of the traveler ring below the path of the traveler. The vertical extent of said shield in some cases maybe varied but it is desirable that it extend from the base or support upwardly to substantially the path of the traveler and to terminate just below the path of the traveler, so that the traveler does not contact therewith in its rotation.

In the preferred embodiment of my invention it is exceedingly important that the shield extend upwardly to substantially the path of the traveler so as to exclude lint, etc., from the entire outer face of the ring that is below the path of the said traveler. Moreover the traveler keeps free from lint, etc., that portion of the traveler ring just below the traveler race, so that the traveler and the shield 13 combine to keep the outer surface of the traveler ring clear and free from foreignmatter. Preferably, the shield 13 is of such interior diameter that the traveler ring does not contact therewith at any time, that is, neither when the ring is' stationary nor when it has risen upon or with respect to the lips 8 in rotation. While I am not limited to a shield, such as 13, noncontacting with the outer face of the traveler ring, yet by locating the said shield so that the traveler ring cannot contact therewith, it is evident that said shield is not subjected to wear, and hence maintains an unvarying relation with respect to said ring, and therefore at all times excludes lint therefrom.

The shield 13 is preferably made as a continuous ring of sheet steel or other suitable metallic matter, and is represented as provided with a base flange 14 fitting upon the flange 4 of the base or support, and also provided with slots 15 to receive the screws 6 by which the base or support is secured to the ring rail. Preferably, also said base 14 is slotted as indicated at 16 for the passage of the traveler clearer 7, as indicated in Fig. 1, or if desired the traveler clearer may be struck up from or otherwise formed upon the shield 13 itself. In the event that the traveler ring is provided with exterior supports or guides instead of interior supports or guides, as represented in this embodiment of my invention, it is evident that the character of the shield 13 would be modified to accord therewith.

In order to exclude lint and the like from the inner face of the traveler ring substantially below the path of the traveler as well as from the interior bearing or guides for the ring, I have in this embodiment of my invention provided an interior ring 17 represented as split at 18, so that it may be sprung within the traveler ring and its supports and held fast with respect thereto While said 130 against the base or support.

split ring 17 may be of any suitable material, I preferably form it of sheet steel of suitable thickness. Preferably, however, it is made so thin that it does not extend radially within the inner edge of the traveler race 10 as is evident from an inspection of Fig. 5, wherein that portion of said ring 17 that is of least diameter is represented as vertically in line with the inner edge of the traveler race 10. It is evident that said ring 17 may be of any suitable extent and form, but herein I have represented the same as having an outwardly extending base flange 19 and the portion of the ring there above as outwardly flaring as indicated at 20. Preferably the said ring 17 extends upward to substantially the top of the lips or guides 8 and at the upper edge thereof may be provided with a slight outwardly extending flange 21 resting upon the upper edge of said lips, but preferably not contacting with the inner face of the traveler ring. It will be noted that said ring 17 extends upward to a point just below the path of the traveler, so that it effectively shields the entire inner face of the ring below said traveler path. It will be evident therefore that the traveler ring in its rotation contacts only with the base or support, and preferably not with the shielding means either exteriorly or interiorly of the ring. Moreover, since the only rotary portions of the device are the traveler ring and its traveler, my invention presents no parts tending to attract or gather lint and other foreign matter.

It is evident that the ring 17 may be otherwise formed than as shown. For example, the split portion thereof may be formed as a tongue and groove, as represented at 22 in Fig. 7, or said ring may be split upon an incline as represented at 23 in Fig. 8, and preferably with the split edge slanting inwardly in the general direction of the rotation of the ring and its traveler, so that there is no tendency of the traveler to catch upon the split portion of the said ring 17.

It is evident from the foregoing description that the ring embodying my invention is of exceedingly simple construction, all complexity of parts being avoided, and that the ring both exteriorly and interiorly thereof as well as the ring guiding means, are effectively shielded from lint, etc. Furthermore, since neither the interior ring 17 nor the exterior ring 13 constitutes any portion of the ring guiding or supporting means, it is evident that there is no wear upon either of said shielding rings 13 or 141, and thatthey maintain an unvarying relation with respect to the traveler rin Moreover, by so constructing and positioning the shielding ring 13 that it is at all times free from contact with the traveler ring, there is no undue strain imposed upon the yarn as would be the case were the traveler ring to engage exteriorly with a surface of larger diameter.

Although I have herein represented the shielding means as applied to a. rotary ring of substantially the form shown in the Brigham Patent, No. 956,930, it is, of course, evident that my invention is in no wise restricted in its use to such form of ring, but that the herein described shielding means may be applied to any suitable or desired form of rotary ring.
